VEHICLE LOADING AND TOWING

Trailer TowingYou can use your SUZUKI to tow a trailer,
but you should always observe the require-
ments and recommendations in this sec-
tion. If you intend to tow a trailer, it is
essential to select a trailer and trailer tow-
ing equipment which are compatible. A
reputable trailer dealer can help you.
For Automatic transmission vehicles, shift
into “3” (Low 2) or “L” (Low 1) (if necessary)
and frequently monitor the coolant temper-
ature gauge when towing up a steep hill. If
the gauge indicates overheating, park the
vehicle in a safe place and let the enginecool down. Refer to “If the Engine Over-
heats” section for details on how to deal
with overheating.
HitchesUse only a trailer hitch bracket that is
designed to bolt to the frame of your vehi-
cle, and a hitch that is designed to bolt to
this bracket. We recommend that you use
a genuine SUZUKI trailer hitch bracket and
trailer hitch (available as options), or equiv-
alent.Safety ChainsAlways attach safety chains between your
vehicle and trailer. Cross safety chains
under the tongue of the trailer so that the
tongue will not drop to the road if the trailer
becomes separated from the hitch. Follow
the manufacturer’s recommendation for
attaching safety chains. Always leave just
enough slack to permit full turning. Never
allow safety chains to drag on the road.
Trailer LightsMake sure your trailer is equipped with
lights which meet federal, state and local
requirements. Always check for the proper
operation of all trailer lights before you
start to tow.Brakes CAUTION
Trailer towing puts additional stress
on the engine, drive train and brakes
of your vehicle. Never tow a trailer
during the first 960 km (600 miles) of
vehicle operation.
CAUTION
Because towing a trailer puts addi-
tional stress on your vehicle, more
frequent maintenance will be
required than under normal driving
conditions. Follow the schedule for
Maintenance Recommended Under
Severe Driving Conditions or perform
more frequent maintenance as nec-
essary.
CAUTION
Towing in “D” range up a steep hill
can cause coolant overheating which
may result in engine/automatic trans-
mission damage.
WARNING
Never use a bumper hitch or a hitch
which attaches to the axle of your
vehicle.
WARNING
Never attach safety chains to the
bumper of your vehicle. Secure con-
nections so that they can’t come
loose.
WARNING
Never splice trailer lights directly into
your vehicle’s electrical system, or
electrical system damage may occur.
WARNING
If trailer brakes are used, you should
follow all instructions provided by the
manufacturer. Never tap into the
brake system of your vehicle.

WARNING
(Continued)
 Avoid “riding” the brakes. “Riding”
the brakes could cause the brakes
to overheat, resulting in reduced
braking efficiency. Use engine
braking as much as possible.
 Because of the added trailer
weight, your engine may overheat
on hot days when going up long or
steep hills. Pay attention to your
engine temperature gauge. If it indi-
cates overheating, pull off the road
and stop in a safe place. Refer to
the “If the Engine Overheats” in
“EMERGENCY SERVICE” section
for details on how to proceed.
WARNING
When parking your vehicle and con-
nected trailer, always use the follow-
ing procedure:
1) Apply the vehicle’s brakes firmly.
2) Have another person place wheel
chocks under the wheels of the
vehicle and the trailer while you
are holding the brakes.
3) Slowly release the brakes until the
wheel chocks absorb the load.
4) Fully engage the parking brake.
5) Manual Transmission – Shift into
Reverse or first gear and turn off
the engine.
Automatic Transmission – Shift
into Park and turn off the engine.
6) If you have a 4-wheel drive vehi-
cle, make sure the transfer switch
is not in “N” (Neutral).
(Continued)
WARNING
(Continued)
When starting out after parking:
1) Push in the clutch (if equipped)
and start the engine.
2) Depress the brake pedal, shift into
gear, release the parking brake
and slowly pull away from the
chocks.
3) Stop, apply the brakes firmly and
hold the brakes while you have
another person remove the
chocks.

Drive BeltMake sure the drive belt tension is correct.
If the belt is too loose, insufficient battery
charging, engine overheating, poor power
steering, poor air conditioning or excessive
belt wear can result. When you press the
belt with your thumb midway between the
pulleys, there should be a deflection
according to the following chart.
The belts should also be examined to
ensure that they are not damaged.
If you need to replace or adjust the belt
have it done by your SUZUKI dealer.

Engine Oil and FilterSpecified Oil
52D083
(1) Preferred
Use engine oil with the American Petro-
leum Institute Certified For Gasoline
Engines “Starburst” symbol.
Select the appropriate oil viscosity accord-
ing to the above chart.
We highly recommend you use SAE 5W-
30 oil.
WARNING
When the engine is running, keep
hands, hair, clothing, tools, etc. away
from the moving fan and drive belts.

Engine Coolant
64J151
60A208
Selection of CoolantTo maintain optimum performance and
durability of your engine, use SUZUKI
Genuine Coolant or equivalent.
This type of coolant is best for your cooling
system as it:
 Helps maintain proper engine tempera-
ture.
 Gives proper protection against freezing
and boiling.
 Gives proper protection against corro-
sion and rust.
Failure to use the proper coolant can dam-
age your cooling system. Your authorized
SUZUKI dealer can help you select the
proper coolant.
Engine Coolant Level CheckCheck the engine coolant level at the
reserve tank, not at the radiator. With the
engine cool, the engine coolant level
should be between the “FULL” and “LOW”
marks.Adding Engine CoolantIf the engine coolant level is below the
“LOW” mark, more engine coolant should
be added. Remove the reserve tank cap
and add engine coolant until the reserve
tank level reaches the “FULL” mark. Never
fill the reserve tank above the “FULL” mark.
EXAMPLE
FULL
LOW
CAUTION
To avoid damaging your cooling sys-
tem:
 Always use a high quality ethylene
glycol base phosphate type coolant
diluted with distilled water at the
correct mixture concentration.
 Make sure that the proper mix is 50/
50 coolant to distilled water and in
no case higher than 70/30. Concen-
trations greater than 70/30 coolant
to distilled water will cause over-
heating conditions.
 Do not use straight coolant nor
plain water.
(Continued)
CAUTION
(Continued)
 Do not add extra inhibitors or addi-
tives. They may not be compatible
with your cooling system.
 Do not mix different types of base
coolants. Doing so may result in
accelerated seal wear and/or the
possibility of severe overheating
and extensive engine/automatic
transmission damage.

10-5EMERGENCY SERVICE
66J22-03E
If the Engine is FloodedIf the engine is flooded with gasoline, it
may be hard to start. If this happens, press
the accelerator pedal all the way to the
floor and hold it there while cranking the
engine. (Do not operate the starter motor
for more than 15 seconds).
If the Engine OverheatsThe engine could overheat temporarily
under severe driving conditions. If the
engine coolant temperature gauge indi-
cates overheating during driving:
1) Turn off the air conditioner, if equipped.
2) Take the vehicle to a safe place and
park.
3) Let the engine run at normal idle speed
for a few minutes until the indicator is
within the normal, acceptable tempera-
ture range shown by the white band
between “H” and “C”.If the temperature indication does not
come down to within the normal, accept-
able range:
1) Turn off the engine and check that the
water pump belt and pulleys are not
damaged or slipping. If any abnormality
is found, correct it.
2) Check the coolant level in the reservoir.
If it is found to be lower than the “LOW”
line, look for leaks at the radiator, water
pump and radiator and heater hoses. If
you locate any leaks that may have
caused the overheating, do not run the
engine until these problems have been
corrected.
3) If you do not find a leak, carefully add
coolant to the reservoir and then the
radiator, if necessary. (Refer to “Engine
Coolant” in the “INSPECTION AND
MAINTENANCE” section.)
WARNING
If you see or hear escaping steam,
stop the vehicle in a safe place and
immediately turn off the engine to let
it cool. Do not open the hood when
steam is present. When the steam
can no longer be seen or heard, open
the hood to see if the coolant is still
boiling. If it is, you must wait until it
stops boiling before you proceed.
Also, be careful not to touch hot
engine parts (radiator, water hoses,
engine etc.).
If the Engine is Flooded: 2, 9
If the Engine Overheats: 2, 9
